課程概述

In this class you will learn the basic principles and tools used to process images and videos, and how to apply them in solving practical problems of commercial and scientific interests. Digital images and videos are everywhere these days – in thousands of scientific (e.g., astronomical, bio-medical), consumer, industrial, and artistic applications. Moreover they come in a wide range of the electromagnetic spectrum - from visible light and infrared to gamma rays and beyond. The ability to process image and video signals is therefore an incredibly important skill to master for engineering/science students, software developers, and practicing scientists. Digital image and video processing continues to enable the multimedia technology revolution we are experiencing today. Some important examples of image and video processing include the removal of degradations images suffer during acquisition (e.g., removing blur from a picture of a fast moving car), and the compression and transmission of images and videos (if you watch videos online, or share photos via a social media website, you use this everyday!), for economical storage and efficient transmission. This course will cover the fundamentals of image and video processing. We will provide a mathematical framework to describe and analyze images and videos as two- and three-dimensional signals in the spatial, spatio-temporal, and frequency domains. In this class not only will you learn the theory behind fundamental processing tasks including image/video enhancement, recovery, and compression - but you will also learn how to perform these key processing tasks in practice using state-of-the-art techniques and tools. We will introduce and use a wide variety of such tools – from optimization toolboxes to statistical techniques. Emphasis on the special role sparsity plays in modern image and video processing will also be given. In all cases, example images and videos pertaining to specific application domains will be utilized....

Really a great course, with focus on the concepts and mathematics of image processing . More academic type course rather than a hands on one. Less weight given to video processing. I wish there was a bit more programming and practical assignments to accompany this compendium of DSP knowledge .

Thanks alot!

It was getting tougher as the course went on. As I am an undergrad Student who has just completed my B.E from India, some of the concepts were totally new to me. May be people studying higher courses and undergoing specialization in this subject might understand them. Overall a very good course.

The hardest course I took on coursera. Even though I find the course contents very informative, the material was in my opinion insufficient to complete all the assignment with the highest grade. I do not find the course to be self contained. It was anyway great as introduction to the topic.

Though some of the parts still require a lot of extracurricular readings, this course is nice and the professor is truly an expert in this area. If you have enough patience and pay efforts to finish it all, it will build a strong foundation for the further study of image processing.

Good course, could have provided more examples and more elaboration regarding the fourier transform. Good instructor who is knowledgeable about this field. Might be better to introduce tutorials that go through selected problems step by step. Thanks very much and all the best.

I have enjoyed this course very much because it is part of my specialist in Electronic and Communications Engineering . Regardless of some concepts and equations that did not reach them clearly, But in the end the amount of benefit is great. thank you

The Course is very informative and definitely a good basic course to image and video processing. However, I felt that linking the course modules with python snippets for examples will help the people who work in the related fieds. Thank you.

it's a good material and nice professor, but sometimes the material is rather theoretical. Some lessons are very heavy with details and very basic practice excercises. I was missing deeper excercises that cover more of the studied material

This course is great for getting an overview of Digital Image Processing.

Some more homework coding practice assignment can be added for getting for intuitive learning experience.

Overall it is awesome for a starting point.

The course was very thorough and helped us understand various basics that are required for further application in various fields. Clear oration accompanied by the slides kept the course interesting and informative

Quite allright for an introductory course to image processing! But to really understand the course, one needs to have experience in basic DSP and statistics. Otherwise, many of material won't be as clear.

Highly relevant and comprehensive, covering important information in the field. Can be improved however by incorporating code using other language libraries besides MATLAB (e.g. Python, etc).

Accent was a bit hard to understand for me, I used google to study separate topics and then gave assignments. Helpful as a guide to direct you what all to study in the space.

Wonderful course....The mentor is knowledgable....the only drawback I find is it we dont find the answers to the assignment questions even after passing it.

A lot of materials and useful information, but some part gets a little overwhelming. Would also like to see image registration explained more.

I think the teacher should speak more clearly, he has a strong accent, however, the materials and contents in this lessons are pretty good.

I cannot understand what the teacher says because of the accent, in the first time I thought it's not a problem but actually I was.

This course is rich in supplemental slides though the assignments are not very useful for understanding the materials.
